ci: k8s: AUTO_GENERATE_POLICY for coco-dev

Re-enable AUTO_GENERATE_POLICY for coco-dev Hosts, unless PULL_TYPE is
"experimental-force-guest-pull", or the caller specified a different
value for AUTO_GENERATE_POLICY.

Auto-generated Policy has been disabled accidentally and recently for
these Hosts, by a GHA workflow change.
